The mdsync course of runs incessantly and prevents the Mac from sleeping. I presently have 4 SSD drives connected through USB to my Mac as Time Machine backup storage. Beforehand mdsync would run shortly on the SSD drives then terminate, however now it appears to run for intervals of time that might be measured in days. As a result of mdsync prevents the Mac from sleeping, this successfully retains my Mac on repeatedly.
This mdsync downside has been impacting me for years. I used to make use of a NAS for Time Machine storage, however mdsync would run for twenty-four+ hours after every backup. This is able to preserve each the Mac and the NAS working across the clock so I finished backing as much as the NAS over a 12 months in the past. By switching to solely backing as much as domestically linked SSD drives, I used to be capable of knock mdsync run instances all the way down to round an hour. However run instances for mdsync (on SSD storage) have elevated during the last 12 months to the purpose the place I’m not again in the identical scenario that I used to be earlier than – i.e. the Mac by no means goes to sleep as a result of mdsync is at all times working. I can now not “repair” the issue by throwing increased velocity storage at it.
Any concepts on the right way to tame the unruly mdsync can be appreciated.
